JZL Insulating Oil Regenerating Discoloration Vacuum Oil purifier
It mainly used in the purification treatment of deteriorated and deteriorated electrical insulating oil and its low viscosity lubricating oil. Based on the application of vacuum drying principles, precision filtration technology, and gas extraction projects, adsorption and percolation refining technologies are an addition. It can be used as a special filtering device for electrical equipment overhaul. It can not only efficiently remove moisture, particulate matter and gas in oil, but also remove free carbon in oil and acid, decolorize and reduce dielectric loss. The performance of the oil is restored, so that the water content, gas content, acid value, PH value and pressure resistance of the treated oil comply with national standards.

Working Principle
The oil enters the pre-stage filter through the oil inlet under the negative pressure formed by the vacuum system of the oil filter, and the large particles of impurities are filtered out; then the oil is heated by the heater and then enters the vacuum tank, using vacuum flash evaporation Technology to remove the residual trace water in the oil, the evaporated water is cooled by the condenser or discharged by the vacuum system; the oil removed from the water is output by the oil pump and enters the regeneration device, the polar substances in the oil are adsorbed and removed, and finally the oil After entering the secondary and fine filters, the particles are filtered out to be purified oil, and the entire purification process is completed.
Features And Advantages
- Adopting polymer magnetic materials imported from Germany as filtering equipment, multi-level precision filtration, and step-by-step encryption, on the one hand, to ensure high filtration accuracy, so that after filtering, the particle size of impurities ≤1-5μm, cleanliness ≤6; The high-quality filter element has a large dirt-holding capacity, and the oil processing capacity can reach more than 4000 tons of oil, and is equipped with an automatic backwashing device.
- Using a combination of three-dimensional flash evaporation technology and UK technology, and using high-efficiency degassing components to quickly separate the water and gas in the oil, the degassing and dehydration efficiency is high, the water content in the treated oil is ≤5ppm, and the gas content ≤0.1% This system is maintenance-free.
- The equipment is equipped with an infrared liquid level automatic control device, which automatically adjusts the balance of oil in and out, and truly achieves man-machine separation, making the operation more convenient and reliable. And has a trinity interlocking automatic safety protection function to avoid the adverse effects caused by misoperation.
- Adopt domestic well-known brand appliances as the main control appliances, so as to fully guarantee the high-performance continuous operation of the equipment without failure.
- S-shaped progressively dense carbon fiber heating is adopted to form a safe and reliable heating system. The optimized pipeline design ensures that there is no "dead oil zone", and the oil temperature can be adjusted arbitrarily between 10 ~ 90ºC and heated at a constant temperature. At the same time, according to different climates, there are two heating methods: automatic and manual.
- A special precision oil pump is adopted, with low noise and meeting environmental protection requirements.
- Adopting a unique regeneration system, with strong adsorption capacity and large molecular surface area, it can decolorize and deacidify the degraded transformer oil and switch oil without purification and regeneration without power failure, oil change and normal operation of the transformer.
- In addition to oil filtering, the transformer can also be filtered online (that is, it can be processed without the transformer stopping work), and has the functions of vacuum oil filling and vacuum drying of the transformer.
- The machine has the characteristics of small size, high efficiency and convenient movement, and the characteristics are suitable for live operation on site.
